To provide a formed body having excellent adhesiveness between rubber-reinforcing fiber and rubber, and a method of producing the formed body.SOLUTION: A formed body including a rubber-reinforcing fiber which has an adhesive component at least on a part of a fiber surface; and rubber, in which the adhesive component includes: a polymer which has one or more kinds of multiple bond selected from reactive carbon-carbon double bond and reactive carbon-carbon triple bond at least in a molecule; and plasticizer which has 5.0% or more of the degree of swelling to the rubber calculated by formula (1) below. (the degree of swelling to the rubber)(%)=(M-M")/M"×100 (1) (in the formula, M denotes a mass (g) of rubber piece having the volume 1.1 cm3 after the rubber piece is immersed in plasticizer at 60°C for 42 hours, and M" denotes a mass (g) of rubber piece having the volume 1.1 cm3 before it is immersed in the plasticizer.SELECTED DRAWING: None
